Sports Board Leash Cuff With Precurved Insert And Overlapping Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports board leashes lack an effective and comfortable design for securing the board to the user's limb, particularly around the ankle, which can lead to discomfort and increased risk of the board being swept away during use.
Innovation Solution
A cuff assembly with a precurved molded insert and overlapping wings that secure around the user's limb, featuring a hook-and-loop closure and a horn for attaching to the leash cord, providing a comfortable and secure fit while minimizing drag and shock distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional rope or cord leash is used, then the board can be tethered to the user, but the board may be swept away during use due to insufficient securing
Solution Approach 1:
The cuff assembly is divided into multiple functional segments: a central section for anatomical fit, wing sections for securing, and a closure mechanism for fastening. This segmentation allows each part to perform its specific function optimally, ensuring reliable board retention while maintaining comfort and ease of operation.
Solution Approach 2:
The cuff assembly incorporates curved and contoured surfaces that conform to the natural anatomy of the user's limb. The curved closure mechanism and contoured wing sections distribute pressure evenly, providing a secure fit that prevents the board from being swept away while maintaining comfort during use.
2Reliability
If the cuff assembly is made secure and comfortable, then board loss is prevented, but drag and wear on the board increase
Solution Approach 1:
The cuff assembly applies different properties to different sections: the central section provides anatomical fit and pressure distribution, the wing sections provide securing force, and the closure mechanism provides fastening. This local differentiation ensures secure board retention while minimizing overall drag and wear on the board through optimized contact points and material selection.

AI summary
Cuff assemblies for sports board leashes, where the cuff assembly includes a central section that having a precurved molded insert that is configured to connect to a cord of the sports board leash, a first wing attached to a first side of the central section, and a second wing attached to a second side of the central section. The maximum width of the central section of the cuff assembly is greater than the maximum width of either of the first wing or second wing, and the first wing and second wing are configured to overlap and fasten to each other in order to secure the cuff assembly around a person's limb portion.
